Abstract |
Activities at a former fire training area at Westover Air Reserve Base (ARB) in Massachusetts resulted in contamination of shallow soils and ground water with a mixture of fuel hydrocarbons and chlorinated aliphatic hydrocarbons (CAHs). Extensive hydrogeologic and geochemical data were collected in May 1995 and in July 1996. A numerical ground water model calibrated using hydrogeologic and geochemical data collected in 1995 was constructed to estimate the fate and transport of the dissolved BTEX compounds. Data collected during the second sampling round was used to assess the accuracy of model predictions and to confirm the effectiveness of natural attenuation processes. Data suggest that BTEX compounds are degrading through aerobic respiration and the anaerobic processes of ferric iron reduction, denitrification, sulfate reduction, and methanogenesis. A solute fate and transport model predicted that BTEX contaminant levels would increase over a 5-year period due to leaching of contaminants from soils into ground water. |
